Get more help from Chegg. Which is the oxidizing agent in the combustion of methanol? So, in O3 -> O2, there are no electrons transferred. For this reason it has oxidation properties but no reducing properties. If it is a molecule (subscript) then include the oxidaiton number of all the atoms. There is a rare case when an oxygen is with another oxygen as the anion, peroxide, O 2 2–. The convention is that the cation is written first in a formula, followed by the anion. To find this oxidation number, it is important to know that the sum of the oxidation numbers of atoms in compounds that are neutral must equal zero. And we talk about oxidation states when we write this little superscript here. In this case, the oxygen has an oxidation state of +2. When bonded, the oxidation number of oxygen is always -2. It is less stable than O2. The O2 molecule is the most stable arrangement of oxygen atoms. In the compound "O=-2 and Mg=+2" There is a general rule that the sum of the oxidation numbers for a pure compound is always zero There rule for oxygen which states that the oxidation number always equals -2 in compounds , except in peroxides So (-2)+("oxidation number of Mg")=0 rArr-2+2=0 So, the oxidation number for "O"=-2 and "Mg"=+2 , the superscript will be the oxidation number of the periodic table, is a strong acid when with!
